LDD stands for Long Distance Dedication...as used by Casey Kasem, Ryan Seacrest, or, most recently, on "Radio with a Twist," the nation's first syndicated gay-friendly radio show.
"This is an LDD, our twist on Long Distance Dedications, going out from John to his long-time boyfriend Noah in Nebraska."

I went to the doctor and told him that I sit at home all day on the couch in my boxers and he diagnosed me with LDD - Lazy Deficit Disorder.
